Much has been written on the importance of the Internet for the trade unions revitalisation but less is known on the perception of workers on how the Internet is being used by trade unions, especially considering the heterogeneous composition of the labour force. In this sense, we conducted a survey in a Southern European country where protests in the education sector have increased in recent years as a reaction to austerity policies. Our findings stress that both unionised and non-unionised, ‘permanent’ and ‘flexible’ school teachers consider that the Internet may allow an easier and broader participation on union debates. Moreover, they support the possibility of a pre-strike ballot using an electronic device. In fact, only board members remain uneasy with such developments.
